The perceived heaviness of an object is not perfectly correlated with an object’s mass. For example, larger objects are perceived as lighter than smaller objects when mass is held constant (Charpentier, 1891). Both non-visual (i.e., touching or wielding an object out of view) and multimodal (i.e., vision + touch) heaviness perception seem to be related to an object’s rotational inertia—the object’s resistance to applied wielding torque (e.g., Amazeen & Turvey, 1996; Streit, Shockley, and Riley, 2007). Inertia models have explained instances of non-visual influences of size because for objects of a given mass, rotational inertia necessarily changes with changes in object size. Efforts have been made to understand the role of vision in heaviness perception based on rotational inertia and its corresponding relation to an object’s kinematics (i.e., motion) (Streit, 2008; Streit et al., 2007). Streit (2008) discussed the importance of applied wielding torque in the proposed multimodally specified inertia model. Specifically, he looked at visual heaviness perception in which a perceiver’s heaviness report was based on watching the wielding motions produced by another actor. Visual perception of others’ actions depends on the perceiver’s action system and changes online as a perceiver’s action capabilities change (see Richardson, Fajen, Shockley, Riley, & Turvey, 2008 for a review). The current study tested the possibility that one’s force production capabilities scale visual heaviness reports by having participants estimate the heaviness of visually viewed objects while wielding objects at different frequencies and orientations to vary applied wielding torque. When objects were wielded at a fast frequency in a vertical orientation, the viewed objects appeared heavier than when wielded at slower frequencies in the same orientation. However, no influences of applied wielding torque were found in the horizontal orientation nor as a function of object orientation. These results suggest that a sufficient change in applied wielding torque relative to overall wielding torque influence visual heaviness perception in a manner consistent with inertia models.
